Ravens rookie offensive tackle Kelechi Osemele was certain he had broken his right ankle when he was carted off the field in the first half and brought to the locker room for further examination.
Osemele's right leg crumpled when several players hit him from behind in a pile. However, X-rays determined that it was just a sprained ankle and Osemele returned to play in the second half.
While Osemele was sidelined, left tackle Michael Oher shifted over to the right side in place of the rookie second-round draft pick. Former Pro Bowl blocker Bryant McKinnie stepped in at left tackle.
"I felt a pop in my knee and my ankle, and I was really worried about it," Osemele said. "I couldn't feel anything. I had so much adrenaline going. I lost so much strength. I definitely thought something was damaged.
"Nothing was broken. I got some [pain-killing] shots in me. Once the pain went away, I finished up the game. I was pretty surprised when the X-rays came back. It was a blessing."
A Houston native, Osemele had several family members in the stands attending the game.
He was hoping to contact them before boarding the Ravens' private charter flight back to Baltimore.
"I'm sure they're worried," he said. "I haven't talked to them yet."
Harbaugh was impressed by Osemele going back in the game after appearing at first to have suffered a serious injury.
"He's a tough guy," Harbaugh said. "K.O.'s got a big heart. Seemed like he played pretty well even with that ankle."
